Off-the-plan: the four risks worth pricing in.

Editorial team, Lawyer Reviews Australia. Reviewed by an admitted Australian property lawyer (NSW) prior to publication.

The four ways off-the-plan purchases go wrong — and the clauses to negotiate before you exchange.

Off-the-plan purchases involve exchanging on a property that doesn’t yet exist, often with settlement 18 months to 4 years away. Four specific risks come up repeatedly. Each can be partly managed by the contract clauses you negotiate up front.

1. Sunset clauses

A "sunset clause" is the longstop date by which the developer must complete and register the plan. If they don’t, either party can rescind. NSW reformed this in 2015 (Conveyancing Amendment (Sunset Clauses) Act 2015) so that developers can no longer unilaterally rescind without Supreme Court order or buyer consent — reducing the practice of developers walking away from contracts when market values rose. Victoria and other states have followed.

What to negotiate: the longest sunset date you can get (24 to 36 months is standard, 48 months is common for larger developments). The longer the period before sunset, the less likely you are to be caught out by a delayed build.

2. Build quality and the right to inspect

The default off-the-plan contract gives the buyer very limited inspection rights. The developer typically certifies completion and the buyer is required to settle on a property they have seen only as a marketing example or display unit. Quality defects that emerge after settlement are pursued under statutory warranties (the Home Building Act 1989 (NSW), the Domestic Building Contracts Act 1995 (VIC), etc.) and developer warranty schemes.

What to negotiate: a pre-settlement inspection right, a defect rectification period, and clarity on the warranty cover that survives settlement.

3. The valuation gap at settlement

Banks lend against the property’s value at settlement, not at exchange. If the market falls between exchange and settlement (as it did in some Sydney and Melbourne markets in 2018–19 and again in 2022), the bank’s valuation may come in below the contract price, and the buyer is left to make up the shortfall in cash. Buyers should stress-test their cash position assuming a 10–15% valuation gap.

What to negotiate: nothing directly — the contract is what it is — but you should size your deposit and your cash reserves to survive a valuation gap of that magnitude.

4. Finance pre-approval expiry

Pre-approvals typically run 3 to 6 months. An off-the-plan settlement 24 months out means re-applying for finance closer to settlement. Your circumstances may have changed (income, age, debts, lending policy). The contract is unconditional on finance — you cannot rescind for inability to fund.

What to negotiate: lender choice flexibility, deposit bond eligibility, and (if cash is tight) a longer settlement period to allow you to organise finance closer to the day.

When the math doesn’t work

Off-the-plan can be the right purchase — stamp duty concessions in many states, first-mover advantage in new precincts, and price certainty in rising markets. But for many buyers, particularly first-home buyers stretching their cash position, the four risks above compound. Buying an established home with documented condition and a 6-week settlement is often the lower-risk path.
